Tip - Make your friends, family your WRITERS!
Do you have friends and family with a good level of English? If they can write start with a minimal of 1 blog from them per day, give them a time frame every day to when they must produce. Give them that extra bit of "being a part of your blog" by making sure the blog is submitted under there name. Not only will you be getting a free blog post done but they will also push it via social media themselves because it has there name on the blog.
A WIN-WIN SITUATION !
